Geometrical and dimensional Measurement Planning: - a systematic and holistic approach

2011 (English)Licentiate thesis, comprehensive summary (Other academic)
Abstract [sv]

För att försäkra sig om den slutliga kvaliteten på maskinbearbetade komponenter måste tillverkande företag mäta och verifiera de geometriska och dimensionella egenskaperna på komponenter innan dem skickas vidare nedströms till den mer värdeskapande monteringen. Det är idag vanligt att den geometriska och dimensionella mätningen och verifieringen uppstår varje gång då en maskin ställs om, när man startar om eller startar upp en ny produktionslina eller då en produktionsprocess ändras. Produktionsteknisk mätteknik och resultat från utförda mätningar används sedan som indata för statistisk processtyrning och övervakning av produktionsprocesser. Syftet med vår forskning har varit att först ta fram en nulägesbild av mätteknisk beredning inom fordons- och flygindustrin och utifrån den identifiera framtida trender med behovsanalys och gap. Utifrån analysen har vi sedan utforskat och utvecklat en modell och metodik för mätteknisk mät- och styrbarhetsberedning. I denna licentiat avhandling har vi utforskat området geometrisk och dimensionell mät- och styrbarhetsberedning (GMCP - Geometrical and dimensional Measurement and Controllability Planning). Vi presenterar en nulägesanalys av området och vi presenterar en teori med modell och ramverk för GMCP. Vidare har vi utforskat en metodik och verktyg benämnd kvalitetssäkringsmatris (QAM - Quality Assurance Matrix) och som vi lyfter fram i denna avhandling. I slutet av avhandlingen presenteras och diskuteras dem hittills uppnådda resultaten från forskningen och i det sista kapitlet dras slutsatser och den fortsatta forskningen inom ”SIMET-GICP” projektet presenteras.

Abstract [en]

In order to ensure final product quality on machined components, manufacturing enterprises must measure and inspect the geometrical and dimensional characteristics of components before they go into higher-value assemblies. Commonly, the geometrical and dimensional measurement and inspection occurs every time at machine tool set-up, when a line is restarted or if the production process is changed. Production metrology and results from production measurements is used as input data for statistical process control and monitoring of production processes. The purpose of our research has been to firstly perform a state of the art analysis in the area of measurement planning applied in the automotive and aerospace industry. The output from the state of the art study has then been used to identify future trends and needs including a gap analysis. Then we used the analysis to explore and develop a model and methodology for measurement and controllability planning.   In this licentiate thesis we have explored the area of GMCP (Geometrical and dimensional Measurement and Controllability Planning). As a major result in this thesis a state of the art survey on GMCP is presented. Based on the state of the art study a theory and model framework for GMCP has been explored and a methodology and tool called QAM (Quality Assurance Matrix) is highlighted in this thesis. In the end of the thesis we present and discuss the present research results we have accomplished and in the final chapter we draw conclusions and outline the continued research within the SIMET-GICP project.

Abstract [en]

Quality is a pillar for success in every enterprise, and the absolute prerequisite for quality is measurement, but if measurement is actually going to improve quality, a process plan for performing the measurement must be properly defined. Increasingly, measurement process planning is performed semi-automatically in software, and since every software vendor has their own format for measurement process plans, this situation leads to interoperability costs. The eQuiPP (exchange of Quality Measurement Process Plans) specification is proposed as a standard which will reduce interoperability costs. The actual cost resulting from the lack of standardization is most likely enormous even though this cost is difficult to quantify. Standards like eQuiPP, properly defined and implemented, eliminate costs such as: • Information translation • Information quality degradation • Reduced perception of quality • Lack of freedom to choose best-in-class • Restraints on corporate or technical agility • Higher fees due to reduced competition • Reduced product and process innovation • Increased training and license fees • Unnecessary software development • Information access fees (e.g., PMI with CAD) • Information integrity and validation testing • Product delays and lost opportunities • High dependence on vendor viability • Excess support staff and equipment The primary scope of this new proposed standard is currently limited to an XML (eXtensible Markup Language) Schema quality measurement plan export format (XSD, extensible schema definition) for variable and attribute inspection plan processing.

Abstract [en]

The purpose of this paper is to present research results within the field of GMCP (Geometrical and dimensional Measurement and Controllability Planning) applied for complex products. GMCP is a prerequisite activity in modern manufacturing of complex products and components. It is attaining high interest and priority among the manufacturing industry management and this is due to the increased demands and focus on environmental sustainability, cost reduction, quality work and the aim towards zero defects in manufacturing. The necessity of a systematic, holistic and integrated engineering QAM (Quality Assurance Matrix) methodology tool is being presented and discussed. The QAM tool and model was originally an idea derived from Volvo CE in Eskilstuna and was initiated through an ISO 9000 quality revision requirement. The current ongoing SIMET (Swedish Industrial Metrology Forum) research has further developed the ideas and underlying theory with new principles and rules embedded in the model and matrix. The current solution has been developed and implemented in a Microsoft Excel application. However, the long term sustainable and rational solution will preferably be implemented in a database design environment.
